IDK where you live but in most places, a fertility specialist is going to require a referral. It isnt that way where I live, and as long as the place accepts your insurance, you can get in so I am not 100% sure on this. Just based off what I read though (from different ladies around here) most other places health care systems make you see a obgyn first, and then if nothing happens in a year, they refer you to a fs. Sorry If this isnt the case for you.
Just trying to help. Lol
